UNITED STATES' WILLIAM GENTRY SHELTON, F ST. ALOUIS, MISSOURI HAIR-CURLING DEVICE.

Application led May 7, 1926. Serial No. 107,346.

This invention relates to hair-curling devices, and more particularly to a device on which the hair is wound by handxand then tightened by imparting a rotary motion to lone of the elements of the device. The mam object of the invention is to produce a sim-` ple, efficient and durable deviceof this kind. More specifically stated, an ob]ect 1s to provide the device with a very effective means to prevent retrograde motlon of the rotary element. A further object 1`s to produce a device of this kind including a tube containing a rotatable rod with an operating lmember at one end, and a simple connectlng means whereby the operating member is secured to the` tube to prevent longitudinal displacement of the rod. This connectln means preferably comprises a sleeve screwe onto the operating member and interlocked vwith the tube, so as to permit rotation of the operating member and at the same tlme prevent longitudinal displacement of the rod to which the operating member is secured.`

With the foregoing and other objects 1n View, the invention comprises the novel construction, combination and arrangement of parts hereinafter more specifically descrlbed and illustrated in the accompanying draw` ings, wherein is shown the preferred embodl- 3U ment of the invention. However, it is to be understood that the invention comprehends changes, variations and modifications which come-within` the scope of the claims hereunto appended.

device embodying the features of this inven-4 tion, showing a strand of hair wound around the tube.

Fig. II is an enlarged longitudinal section 40 of the device.

Fig. III is an enlarged section on line III-III in Fig. II.

Fig. IV is an enlarged section showing the means for connecting the operating member to the tube and the spring to prevent retrograde motion of the ro A To illustrate the invention, I have shown a tapering tube 1 containing a rod 2 which extends from the lower end of the tube. The extended lower-end ofthe rod is forked, as shown at 3, to receive a string 4 whereby the hair is secured to the rod.

The upper end of the rod is provided with an operating member comprising a knurledknob 5 having a reduced extension 6 which sleeve 7 having an inturned flange 8 which hes inan annular groove in the outer face '5, it preventslongitudinal displacement of vthis. unit and the tube.

Fig. I is a side elevation of a hair-curling is formed integraLwith or otherwise suitably secured tothe rod 2. This extension 6 is threaded to receive an internally threaded of the tube. `The sleeve? is thus rotatabl interlocked with-- the tube 1 to prevent longitudinal displacement of said sleeve, and since thesleeve is secured to the operating member the rod 2 in the tu The rod and its operating member 5 are to be turned in aclockwise direction so the extension 6 is provided with a right-hand thread to prevent unscrewing of the sleeve 7. This sleeve engages an abutment shoulder at the junction of knob 5 and the extension 6,

so as to limit the rotary motion of the threaded sleeve relative to the knob 5. The lower end of the extension 6 is 4separated 'I6 from the tube 1 and it cannot contact with said tube. Therefore the knob 5, its extension 6 and the sleeve z7 rotate as. a unit with very llittle resistance due to friction between The means for preventin retrograde motion of the rod 2 in the tu 1 comprises a.

spring 9 interposed between said rod and tube.. This spring is preferably in the form of a leaf or flat strip of metal coiled around the rod and having its inner end secured to the rod in any suitable manner, for exam le, by means of a rivet 10 shown'in Fig. II. The outer end ofthis spring comprises a coil member surrounding the inner end and frictionally engaging the inner face' of the tube 1. v 5 @wtf Attention is directed to Fig. III which shows how the outer end portion of the spring conforms to and contacts with the tube. The spring tends to expandwlile confined by the tube, but it will slide freely on the tube when the rod is turned in a clockwise direction, for this motion tends to contract 4the spring. However, any effort to turn the rod in the opposite direction oisA vwill tend to expand the spring, and such with the spring 9, can be easily applied to, or Withdrawn from, the tube 2 and sleeve 7, and this spring provides a strong, durable and positive means to prevent retrograde motion of the rod in the tube.

In using the device, the hair is secured to the lower end of the rod 2 by means of the string 4, and the hair is Wound by hand around the tube 1. The upper end of the hair can then be secured by means of a string as shown in Fig. I, or in any other` suitable manner. The next step consists in tightening the hair on the tube, and this can be accomplished b v firmly holding the tube l and turning the knob 5, or by holding the knob and turning the tube. During the tightening operation, the spring 9 prevents retrograde motion, and after this operation is completed the spring will securely hold the hair in its tightened condition for an indefinite period.

I claim:

1. A hair-curling device comprising a tube on which the hair is Wound, a. rod rotatably mounted in said tube, said rod having an end extending from the tube and adapted to be'seeured to the hair, and a leai` spring in the form of a coil tending to expand between said rod and tube to prevent rotation in one direction, said leaf spring having an inner end secured to said rod and an outer coil member surrounding said inner end and conforming to the inner face of said tube, and said outer coil member being in frictional contact with the inner face of said tube.

2. A hair-curling device comprising a tube on which the hair is wound, a rod rotatably mounted in said tube, said rod having an operating member at one end located outside of said tube, the other end ot said rod being extended from the tube and adapted to be secured to the hair, means ior preventing retrograde motion ot' the rod in the tube, and means ior preventing longitudinal displacement ot the rod, the last mentioned means including a sleeve connecting said operating member to said tube, said sleeve being screwed onto said operating member and provided with an inturued liange at its lower end. the tube having an annular groove in which said flange is mounted and the operating member being provided with an abutment engaged by said sleeve to limit the rotary motion ot the sleeve relative to said operating member.

ln testimony that I claim the foregoing I hereunto affix my signature.
